Abstract
INTRODUCTION: Abortion attitudes are influenced by people's socioeconomic and demographic circumstances and can be volatile during times of crisis. Brazil is an interesting case for examining abortion attitudes because of its strict abortion policies, changing religious landscape, high income inequality, and extreme uncertainty generated by the back-to-back Zika and COVID-19 crises. This study seeks to assess Brazilian women's attitudes toward abortion and whether religion and income explain these attitudes in the context of novel infectious disease epidemics. METHODS: We used data from a population-based sample of 3996 women ages 18-34 in Pernambuco, Brazil, collected during the onset of the COVID-19 pandemic (May-September 2020). We conducted paired t-tests and multivariate-adjusted logistic regression models with adjusted Odds Ratios (aORs) and 95% CIs to assess differences in support for abortion in the case of fetal congenital Zika syndrome (CZS), maternal Zika infection during pregnancy, and maternal COVID-19 infection during pregnancy. RESULTS: Significantly more women support the right to abortion in the case of fetal CZS (50%) than in the case of maternal Zika infection (40%) and maternal COVID-19 infection (31%). Support for abortion varies by income and religion. Controlling for other demographic characteristics, high-income women have higher odds of supporting abortion in the case of fetal CZS (aOR = 1.92; 95% CI: 1.25-2.94) and maternal Zika infection (aOR = 2.07; 95% CI: 1.33-3.21) than low-income women. Evangelical women have lower odds of supporting abortion in the case of maternal Zika infection (aOR = 0.65; 95% CI: 0.45-0.93) and marginally lower odds of supporting the right to abortion in the case of maternal COVID-19 infection (aOR = 0.69; 95% CI: 0.47-1.00) than women of other religious affiliations. CONCLUSIONS AND POLICY IMPLICATIONS: With increasingly conservative religious groups gaining size in Brazil, we expect to see increasing abortion restrictions. However, this research finds that a sizable portion of women across all incomes and religious affiliations support abortion, particularly in the case of fetal anomalies associated with Zika.
